Chenxi Qiu


Dr. Chenxi Qiu is currently a tenure-track assistant professor in The Department of Computer Science and Engineering at University of North Texas (UNT). He directs the Mobile Computing Lab (MCLab) at UNT.

Before joining UNT, he worked as an assistant professor in the Department of Computer Science at Rowan University from 2018 to 2021, and worked as a Postdoctoral Scholar in The College of Information Sciences and Technology at Pennsylvania State University from 2016 to 2018.

Dr. Qiu received his Ph.D. degree in The Holcombe Department of Electrical and Computer Engineering at Clemson University in 2015 and his B.Engr. degree in Telecommunication Engineering from Xidian University in China in 2009.

Dr. Qiu’s research interests span the areas of mobile crowdsourcing and vehicle information systems. His research results have been published in highly-competitive conferences and journals (e.g., INFOCOM, AAMAS, SIGSPATIAL, IPSN, ICDCS, CIKM, Transactions on Networking (ToN), Transactions on Cloud Computing (TCC), Transactions on Mobile Computing (TMC), Transactions on Parallel and Distributed Systems (TPDS), and Transactions on Computers (TC)). His CV can be found here.

To prospective students: Multiple research assistant positions are available. I am looking for self-motivated students who are interested in the areas of mobile computing and spatial computing. If you are interested, please e-mail me with your CV and transcripts.
